Cleaning and disinfecting composition

ABSTRACT

The present invention provides a non-cationic antimicrobial agent containing composition which blooms when added to water. The compositions have good cleaning, disinfecting and bloom properties.

The present invention is directed to concentrated cleaning and/ordisinfecting compositions which bloom when diluted in water.

Cleaning compositions are commercially important products and enjoy awide field of utility in assisting in the removal of dirt and grime fromsurfaces, especially those characterized as useful with hard surfaces.One particular category of cleaning compositions are those which providea blooming effect. Such an effect may be described as the change of thewater's appearance from essentially colorless and transparent to that ofa milky white or milky yellowish white, cloudy appearance upon theaddition of an amount of the cleaning composition. This effect is alsosometimes referred to as the “break”. Such blooming is a highlydesirable in such pine oil type cleaning compositions as consumer/enduser expectations associate cleaning effectiveness with the extent anddegree of this blooming upon formation of a cleaning composition. Suchan effect is particularly known and generally associated with pine oiltype cleaning compositions which typically include one or more of thefollowing identifying characteristics: containing an amount of one ormore resins or oils derived from coniferous species of trees; containingnatural fragrances or synthetic fragrance compositions which areintended to mimic the scent of one or more resins or oils derived fromconiferous species of trees; a color ranging from colorless to a deepamber, deep amber yellow or deep amber reddish color; generation of amilky or cloudy appearance when diluted with water in dilutions usefulfor cleaning applications. Such pine oil type cleaning compositions aregenerally provided in a concentrated composition which is subsequentlydiluted with water by an end user/consumer to form a cleaningcomposition therefrom.

Thus, the present invention provides a hard surface cleaning concentratecomposition comprising:

-   -   a) from about 0.05 to about 15 wt %, preferably from about 0.1        to about 8 wt %, and more preferably from about 0.2 to about 6        wt % of at least one non-cationic antimicrobial agent;    -   b) from about 0.1 to about 20 wt %, preferably from about 0.5 to        about 15 wt %, and more preferably from about 1 to about 15 wt %        of at least one solvent selected from water soluble organic        solvent, water insoluble organic solvent, terpene, essential        oil, and mixtures thereof;    -   c) from about 0.1 to about 20 wt %, preferably from about 0.5 to        about 15 wt %, and more preferably from about 1 to about 10 wt %        of an anionic soap surfactant;    -   d) from about 0.01 to about 10 wt %, preferably from about 0.05        to about 8 wt %, and more preferably from about 0.1 to about 5        wt % of at least one surfactant selected from nonionic        surfactant, anionic surfactant excluding the anionic soap of c),        and mixtures thereof;    -   e) optionally, from about 0.1 to about 10 wt % of one or more        alkanolamines;    -   f) optionally, from about 0 to about 10 wt % of one or more        conventional constituents selected from dyes, colorants,        fragrances and fragrance solubilizers/enhancers, light        stabilizers, viscosity modifying agents, pH adjusting agents and        pH buffers including organic and inorganic salts, optical        brighteners, opacifying agents, hydrotropes, antifoaming agents,        enzymes, anti-spotting agents, anti-oxidants, preservatives, and        anti-corrosion agents; and    -   g) the balance, water.

-   -   x is about 5-15, preferably about 15, and    -   y is about 5-15, preferably about 15.

Still further useful nonionic block copolymer surfactants includeethoxylated derivatives of propoxylated ethylene diamine, which may berepresented by the following formula:

where (EO) represents ethoxy,

-   -   (PO) represents propoxy,        the amount of (PO)_(x) is such as to provide a molecular weight        prior to ethoxylation of about 300 to 7500, and the amount of        (EO)_(y) is such as to provide about 20% to 90% of the total        weight of said compound.

Other nonionic surfactants include short chain non-ionic surfactants.The short chain non-ionic surfactant is one which has from six to elevencarbon atoms in the non-polar hydrophobic portion of the surfactant.

For the present invention, the surfactant selected from nonionicsurfactants, anionic surfactants excluding the anionic soap of c), andmixtures thereof is present in an amount of from about 0.01 to about 10wt %, preferably from about 0.05 to about 8 wt %, and more preferablyfrom about 0.1 to about 5 wt %.

An optional, but preferred, constituent in the present invention is analkanolamine, such as, for example monoethanolamine.

As the concentrate compositions are aqueous, water forms a majorconstituent. Water is added in order to provide 100 wt % of theconcentrate composition. The water may be tap water, but is preferablydistilled and/or deionized water. If the water is tap water, it ispreferably appropriately filtered in order to remove any undesirableimpurities such as organics or inorganics, especially mineral saltswhich are present in hard water which may thus interfere with theoperation of the other constituents of the invention, as well as anyother optional components of the liquid concentrates according to theinvention.

Water is added in amounts which are sufficient to form the concentratedcompositions which amount is sufficient to ensure the retention of asubstantially clear characteristic when produced as a concentrate, butat the same time ensuring good blooming upon the addition of theconcentrated composition to a further amount of water, or upon theaddition of further water to the concentrate. This amount may be readilydetermined by first mixing measured amount of the non-water constituentsin a suitably sized vessel and then during stirring adding water.Generally, water is present in the concentrate compositions in amountsin excess of about 50 wt %, preferably in amounts of in excess of about70 wt %, but most preferably in amount of between 80-90 wt % based onthe total weight of the concentrate compositions according to theinvention.

As noted previously, the concentrate compositions according to theinvention may include further optional, but advantageously includedconstituents.

Useful optional constituents are one or more coloring agents which finduse in modifying the appearance of the concentrate compositions andenhance their appearance from the perspective of a consumer or other enduser. Known coloring agents, may be incorporated in the compositions ineffective amount to improve or impart to concentrate compositions anappearance characteristic of a pine oil type concentrate composition,such as a color ranging from colorless to brown to yellow to purplecolor with or without fluorescent ingredients. Such a coloring agent orcoloring agents may be added in any useful amount in a conventionalfashion, i. e., admixing to a concentrate composition or blending withother constituents used to form a concentrate composition. However,other colors atypical of pine oil type and/or lemon oil type cleaningconcentrates may be used as well. Known art light stabilizerconstituents useful in pine oil type compositions may also be added,particularly wherein coloring agents are used in a composition. As isknown to the art, such light stabilizers act to retain the appearancecharacteristics of the concentrate compositions over longer intervals oftime.

Further useful optional constituents which may in some cases bedesirably included in the inventive compositions include rheologymodifying agents such as thickeners.

Other conventional additives known to the art but not expresslyenumerated here may also be included in the compositions according tothe invention. By way of non-limiting example these may includefragrance/fragrance adjusters (which do not interfere with any pine oilconstituent of the present invention, when present and which cangenerally be present in an amount of from about 0.000001 to about 1.5 wt% of the total concentrate, whether pine oil based or non-pine oilbased), pH adjusters, pH buffering agents, non-ionic surfactants andinsect repellants. Such non-ionic surfactants denoted here areconventionally known; examples are described in McCutcheon's Detergentsand Emulsifiers, North American Edition, 2001; Kirk-Othmer, Encyclopediaof Chemical Technology, 4th Ed., Vol. 23, pp. 478-541, the contents ofwhich are herein incorporated by reference. Such optional constituentsshould be selected so to have little or no detrimental effect upon thedesirable characteristics of the present invention, namely the bloomingbehavior, cleaning efficacy, and disinfectant activity, low toxicity asprovided by the inventive compositions. Generally the total weight ofsuch further conventional additives may comprise up to 10 wt % of aconcentrated composition formulation.

What is to be understood by the term “concentrate” and “concentratecomposition” in this specification and claims is the pre-consumerdilution and composition of the cleaning composition which is theessentially the form of the product prepared for sale to the consumer orother end user. Such a consumer or other end user would then normally beexpected to dilute the same with water to form a cleaning composition.It is to be understood however that nothing in this invention would barits use as cleaning composition without any further dilution and it maybe used in the concentrations in which it was prepared for sale.Similarly, what is to be understood by the term “cleaning compositions”are the water diluted compositions which are expected to be prepared bythe consumer or other end user by mixing a measured amount of the“concentrate” with water in order to form an appropriately dilutedcleaning composition which is suitable for use in cleaning applications,especially in the cleaning of hard surfaces.

It is also to be understood, that proportions of one or moreconstituents have been and generally are referred to as percent byweight or as parts by weight based on a measure of 100% by weight,unless otherwise indicated.

As generally denoted above, the formulations according to the inventioninclude both cleaning compositions and concentrates as outlined abovewhich differ only in the relative proportion of water to that of theother constituents forming such formulations. While the concentratedform of the cleaning compositions find use in their original form, theyare more frequently used in the formation of a cleaning compositiontherefrom. Such may be easily prepared by diluting measured amounts ofthe concentrate compositions in water by the consumer or other end userin certain weight ratios of concentrate:water, and optionally, agitatingthe same to ensure even distribution of the concentrate in the water. Asnoted, the concentrate may be used without dilution, i.e., inconcentrate:water concentrations of 1:0, to extremely dilute dilutionssuch as 1:1-1:1000, preferably in the range of 1:5-1:500 but mostpreferably in the range of 1:10-1:100. The actual dilution selected isin part determinable by the degree and amount of dirt and grime to beremoved from a surface(s), the amount of mechanical force imparted toremove the same, as well as the observed efficacy of a particulardilution. Generally better results and faster removal is to be expectedat lower relative dilutions of the concentrate in water.

EXAMPLES

Preparation of Example Formulations:

Exemplary formulations illustrating certain preferred embodiments of theinventive compositions and described in more detail in Table I belowwere formulated generally in accordance with the following protocol.

Into a suitably sized vessel, a measured amount of the non-cationicantimicrobial agent (e.g., PCMX, DCMX) was provided after which theremaining organic based components (e.g., hydrocarbon diluent, pine oil,water soluble organic solvent, dye (if any)). These components werestirred until the non-cationic antimicrobial agent was fully dissolved.The anionic soap surfactant solution is then added to the organicsolution and the components are stirred until the mixture ishomogeneous. The remaining amount of water is then added to theorganic/anionic soap surfactant mixture and the components are thenmixed until the solution is clear and homogeneous. Mixing of the variouscomponents at the various times can range from 5 minutes to 120 minutes;the amount of time can vary so long as particular solutions appeared tobe homogeneous. The exemplary compositions were readily pourable, andretained well mixed characteristics (i.e., stable mixtures), even atelevated temperatures up to 120° F., upon standing for extended periods,even in excess of 90 days.

Compositions of the present invention were evaluated for cleaning anddisinfecting properties.

Cleaning Evaluation

Cleaning evaluations for greasy soils were performed in accordance withthe testing protocol outlined according to ASTM D4488 A2 Test Method,which evaluated the efficacy of the cleaning compositions on masonitewallboard samples painted with wall paint. The soil applied was a greasysoil sample containing vegetable oil, food shortening and animal fat.The sponge (water dampened) of a Gardner Abrasion Tester apparatus wassquirted with a 15 gram sample of a tested cleaning composition, and theapparatus was cycled 10 times. The evaluation of cleaning compositionswas “paired” with one side of each of the test samples treated with acomposition according to the invention, and the other side of the samesample treated with a comparative example's composition, thus allowing a“side-by-side” comparison to be made. Each of these tests wereduplicated on at least 5 wallboard tiles and the results statisticallyanalyzed and the averaged results reported on Table 3, below. Thecleaning efficacy of the tested compositions was evaluated utilizing aMinolta Chroma Meter CF-110, with Data Processor DP-100, which evaluatedspectrophotomic characteristics of the sample.

Cleaning evaluation for oily soil was evaluated on diluted compositionsunder the protocol of ASTM D-4488-89 Annex A5 for particulate soil,which evaluated the efficacy of the cleaning compositions on vinyl tilesamples. The soil applied was a particulate soil sample containingnatural humus, paraffin oil, used crankcase motor oil, Portland cement,silica, lampblack carbon, iron oxide, bandy black clay, stearic acid,and oleic acid produced according to the protocol. Each of the soiledtest vinyl tile samples were placed into the apparatus and the center ofeach tile was wetted with a 20 milliliter sample of a test formulationand allowed to stand for 1 minute. When approximately 30 seconds hadelapsed, a further 50 milliliter sample was applied to the sponge (waterdampened, then wrung to remove excess water) of a Gardner AbrasionTester apparatus. Thereafter the apparatus was cycled 10 times, whichprovided 20 strokes of the sponge across the face of each of the vinyltest tiles. The reflectance values of the cleaned samples at 10 cycleswere evaluated utilizing a Minolta Chroma Meter CF-110, with DataProcessor DP-100, which evaluated spectrophotomic characteristics of thesample.

As generally denoted above, the formulations according to the inventioninclude both cleaning compositions and concentrates as outlined abovewhich differ only in the relative proportion of water to that of theother constituents forming such formulations. While the concentratedform of the cleaning compositions find use in their original form, theyare more frequently used in the formation of a cleaning compositiontherefrom. Such may be easily prepared by diluting measured amounts ofthe concentrate compositions in water by the consumer or other end userin certain weight ratios of concentrate:water, and optionally, agitatingthe same to ensure even distribution of the concentrate in the water. Asnoted, the concentrate may be used without dilution, i.e., inconcentrate:water concentrations of 1:0, to extremely dilute dilutionssuch as 1:1000, preferably in the range of 1:1-1:500 but most preferablyin the range of 1:10-1:100. The actual dilution selected is in partdeterminable by the degree and amount of dirt and grime to be removedfrom a surface(s), the amount of mechanical force imparted to remove thesame, as well as the observed efficacy of a particular dilution.Generally better results and faster removal is to be expected at lowerrelative dilutions of the concentrate in water.

Evaluation of Light Transmittance (“Blooming”) of Formulations

Certain of the formulations described on Table 1 were evaluated todetermine the degree of light transmittance, which conversely provided ameasure of the opacity of each of the aqueous dilutions. The results ofthe light transmittance evaluation was determined as a percentage oflight transmitted through a sample of a particular aqueous dilutionwherein the transmission of a like sample of water is assigned apercentage of 100%. Testing was performed by preparing either a 1:100 or1:200 dilution of the example formulation:water, (tap water) after whichthe sample was mixed for 30 seconds and a transmittance reading wastaken using a Brinkman model PC801 dipping probe calorimeter, which wasset at 620 nm to determine the light transmission of each of thesamples. Readings taken at a water temperature of 20° C. were evaluated,as well as the reference (pure tap water) sample used to calibrate thecolorimeter to the reference 100% light transmission sample outlinedabove. The resulting determined values are reported in Table 4 whichresults provide an empirical evaluation of the degree of transparency ofa diluted example formulation wherein 0% indicates complete opacity and100% the transparency of the sample. Accordingly, a lower reported lighttransmittance value of a particular aqueous dilution provided a moredesirable indication of the blooming characteristic of the particularaqueous dilution. The results are shown in Table 4.
